From Middle English, from Old English līþe ("gentle, mild"), from Proto-Germanic *linþiz, from Proto-Indo-European *lento. Akin to Danish and German lind ("mild"), Icelandic linr ("soft to the touch"). Not attested in Gothic nor Old Norse. Some sources list also Latin lenis ("soft"), others Latin lentus ("supple").

In the morning we awoke in lithe, though fluttered spirits; and after breakfast, in their pleasant kitchen, with "Michael," and "Blue-eye," and "White Lady," and half-a-dozen more purring about us, we took leave of a house where we have enjoyed many pleasant hours, and once more assembled at our own as the final rendezvous.
